Dual-Band Plasmonic Perfect Absorber Based on the Hybrid Halide Perovskite in the Communication Regime

Due to the weak absorption of (CH3NH3)PbI3 in the communication regime, which restricts its optoelectronic applications, we design a adjustable dual-band perfect absorber based on the (CH3NH3</s...

By varying some key structural parameters, the dual-band absorption peaks of (CH<sub>3</sub>NH<sub>3</sub>)PbI<sub>3</sub> can be separately shifted in a wide wavelength region. Moreover, the designed absorber can keep good performance under wide angles of incidence and manifested polarization correlation. Furthermore, not just for (CH<sub>3</sub>NH<sub>3</sub>)PbI<sub>3</sub>, the physical mechanism in this absorber can also be utilized to strengthen the absorption of other halide perovskites.https://www.mdpi.com/2079-6412/11/1/67plasmonicsabsorptionmetamaterialhalide perovskites
